Jose is an exceptional match: he's a proven 0→1 founding engineer with 12 years of shipping production systems, deep full-stack expertise (FastAPI, Next.js, React), hands-on LLM/GenAI experience (LangGraph agents, fine-tuning, RAG), and has already shipped human-in-the-loop AI products at scale. His recent work at Addie building multi-channel AI agents and real-time voice systems directly mirrors the role's requirements for end-to-end AI product development with high ownership.

Hook: You've already solo-shipped a real-time AI product serving 10+ countries—Vertex wants exactly this kind of founding engineer to build the next generation of enterprise AI workflows.

AI Product Engineer application (via HackerNews)
Hi Paul,

Saw the AI Product Engineer role on HackerNews. The description reads like my last year: at Addie I was the sole engineer who went from empty repo to a real-time AI voice platform serving students in 10+ countries — designing the UX, building three Next.js apps, and wiring up LangGraph agents across web, SMS, voice, and WhatsApp.

That work centered on the exact patterns you mention: human-in-the-loop counselor review, decision support, and AI-native interfaces beyond chat (sub-200ms WebRTC voice, not just a text box). I also owned build-vs-buy calls and cost-per-conversation targets — the kind of ownership real enterprise workflows demand.

Before that: LLM-to-SQL agents at Rubercubic, developer platforms at Twilio, and an M.S. in AI from UT Austin.

Happy to walk you through a demo or the architecture whenever works. 

Best,
Jose Oliveros

Vertex Inc https://www.vertexinc.com/ | AI Product Engineer | Full-time | US | $104.9k–$136.4k + bonus

Vertex is hiring an AI Product Engineer to build production AI products for real enterprise workflows.

You’ll work end-to-end: learn the domain, talk to users, design the UX, build the full-stack app, integrate LLMs/GenAI, and ship products used by customers and internal teams. Think human-in-the-loop review, decision support, workflow automation, escalation flows, and AI-native interfaces beyond chat.

This is a high-ownership, high-visibility role for an early-career builder who has already shipped real things. We’re looking for 0–3 years of experience, strong product taste, full-stack ability, hands-on AI/LLM experience, and a portfolio of apps, demos, repos, or case studies.

Bonus: React, Figma, enterprise SaaS/internal tools, workflow products, customer-facing work, or solo-shipped projects.
